USMC011 ‘Marine Flame Thrower’
The ‘M2 Flamethrower’ was the U.S. made, man-portable backpack flamethrower used in WW2.
Although its ‘burn-time’ was just 7 seconds and its range a mere 20-40 yards it was a very useful weapon... especially in close-quarter battle situations such as the ‘island-hopping’ campaign in the Pacific during WW2.
The Marines used it extensively against pill-boxes, bunkers and trenches defended by determined, die-hard Japanese.
